I'm trying to set up a firewall rule to also
allow TCP DNS resolution along with UDP to
get rid of warnings like
WARNING: One or more of your DNS servers does not accept TCP connections. Although rarely used, TCP
connections are occasionally used instead of UDP connections. When firewalls block the TCP DNS
connections, it can cause hard-to-diagnose problems. The problem servers are:
18.104.22.168: Error [Connect fail: 0].
but haven't managed to do it yet. TCP/UDP is not it.
Dedicated rule for TCP and UDP each ain't it either.
